36961por Bordeira Gaspar, Tiago, Sá, Ana, Lopes, José Manuel, Sobrinho-Simões, Manuel, Soares, Paula, Vinagre, João“…Tumour cells can adopt telomere maintenance mechanisms (TMMs) to avoid telomere shortening, an inevitable process due to successive cell divisions. In most tumour cells, telomere length (TL) is maintained by reactivation of telomerase, while a small part acquires immortality through the telomerase-independent alternative lengthening of telomeres (ALT) mechanism. …”

36962por Clemente, Giuliana D., Hannaford, Matthew R., Beati, Hamze, Kapp, Katja, Januschke, Jens, Griffis, Eric R., Müller, Hans-Arno J.“…Knock-down of Spindly in the female germ line results in mitotic arrest during embryonic cleavage divisions. We investigated the requirements of Spindly protein domains for its localisation and function, and found that the carboxy-terminal region controls Spindly localisation in a cell-type specific manner. …”

36963por Bornens, Michel“…Metazoans are unique in making cohesive multicellular organisms through complete cell divisions. They evolved a primary cilium/centrosome (PC/C) organ, ensuring similar functions to the basal body/flagellum of unicellular eukaryotes, but in different cells, or in the same cell at different moments. …”

36964por Tomita, Kazunori“…Telomere length homeostasis is achieved via a balance between telomere lengthening by telomerase, and erosion over successive cell divisions. Impaired telomerase regulation leads to shortened telomeres and can cause defects in tissue maintenance. …”

36965por Hur, Juyoen, Kaplan, Claire M., Smith, Jason F., Bradford, Daniel E., Fox, Andrew S., Curtin, John J., Shackman, Alexander J.“…In short, alcohol transiently reduces reactivity to emotional faces and it does so similarly across the two major divisions of the human EAc. These observations reinforce the translational relevance of addiction models derived from preclinical work in rodents and provide new insights into the neural systems most relevant to the consumption of alcohol and to the initial development of alcohol abuse in humans.…”

36970por Somerville, Vincent, Schwaiger, Michaela, Hirsch, Philipp E., Walser, Jean-Claude, Bussmann, Karen, Weyrich, Alexandra, Burkhardt-Holm, Patricia, Adrian-Kalchhauser, Irene“…DNA methylation is an epigenetic mechanism which is both sensitive to environmental conditions and stably inherited across cell divisions. We therefore investigate early life predisposition in the round goby Neogobius melanostomus by growth back-calculations and then study DNA methylation by MBD-Seq in the brain region controlling vertebrate reproductive behavior, the hypothalamus. …”

The encoded hybrid putative RDases have cytoplasmic or exoplasmic C-terminus localization, and cluster phylogenetically separately from the existing RDase groups. …”

Moreover, we found a large number of retrogradely-stained CTB-positive neurons in La after injecting CTB into A2. …”
